A series of NaYF4: Yb3+
Er3+ nanoparticles with different doping concentration were successfully prepared by the combination of coprecipitation and hydrothermal methods using sodium citrate as chelator. Upconversion luminescence can be observed in all of the samples at room temperature. Fixed the Er3+ concentration with 1 mol% unchanged
the effect of the Yb3+ concentration on the upconversion luminescence of NaYF4: Yb3+
Er3+ samples were studied when the doped Yb3+ concentrations were 0 mol%
1 mol%
2 mol%
5 mol%
10 mol% and 20 mol%
respectively. As increasing the Yb 3+ concentration
the total intensity of the upconversion luminescence of the samples is increasing while the ratio of red to green emission increases firstly and then decreases. The maximum ratio value is 22.1 when the Yb3+ concentration is 10 mol%. It is found that the cross relaxation and cooperative sensitization effect are the reasons for the phenomenon above.

In this paper
we demonstrated the encapsulation of ZnS: Mn2+ nanowires (NWs) and ZnO quantum dots (QDs) with a layer of mesoporous SiO 2 shell for the purpose of integrating dual emission property into one common nanostructure. The average diameter of ZnS: Mn2+ NWs
ZnO QDs
and ZnS: Mn2+ / ZnO@SiO2 heterostructure was about 10 nm
6 nm
and 22 nm
respectively. Within ZnS: Mn2+ / ZnO@SiO 2 nanocomposites
the intensity of the yellow-orange emission contributed by ZnS: Mn2+ NWs and the UV emission contributed by ZnO QDs was three and ten times higher than their individual components
respectively. The fluorescence intensity ratio of the dual emission can be tuned by adjusting the hydrolysis time of tetraethyl orthosilicate. The peak energy of the yellow-orange and UV emission showed blueshift and redshift as increasing the temperature
respectively. The anomalous enhancement of the integrated intensity for the UV emission with the temperature indicated that the high surface state density existing in ZnO QDs can overrun the influence of temperature quenching and even alter the photoluminescent properties. 2010 American Institute of Physics.
